PHP CLI Mode Introduction and use Tutorial

See full name to know, PHP-CLI is the short name of PHP command line interface, that is, the PHP interface, in Windows and Linux are supported PHP-CLI mode, in fact, both, I have written before:

One, window run the PHP program at the command line
Second, Linux uses crontab to achieve timed tasks
Advantages and application of PHP-CLI mode:

• 1. Fully support multithreading
• 2. As above, can achieve the scheduled task
• 3. Developing desktop apps is using PHP-CLI and GTK packages
• Write shell scripts in PHP 4.linux

In fact, PHP operating environment far more than Apache and CLI, haha, such as Aolserver, Apache, Apache2filter, Apache2handler, Caudium, CGI (until PHP 5.3), cgi-fcgi, CLI, continuity, embed, ISAPI, Litespeed, Milter, Nsapi, phttpd, Pi3web, Roxen , thttpd, Tux, and Webjames.

You can use Php_sapi_name () to detect, do not believe, look at the following code:

1. <? PHP
2. /** reprint Please indicate the link: http://www.phpddt.com * *
3. echo Php_sapi_name();

I run on the cmd of Windows:
Use standard input and output:

STDIN Standard input device

STDOUT Standard output device

STDERR standard error device

Look at the results of running the following program:

4. Ask for input
6. Fwrite(STDOUT, "Enter Your Name:");
10. Get input
12. $name = trim(fgets(STDIN));
16. Write input back
18. Fwrite(STDOUT, "Hello, $name!") );

The PHP CLI has two special variables for this purpose: one is the $ARGV variable, which saves the arguments passed to the PHP script as a separate array element through the command line, and the $ ARGC variable, which is used to hold the number of elements in the $ARGV array.
You can run:

1. <? PHP
2. /**
3. * @link http://www.phpddt.com
4. */
5. Print_r($argv);

Look at the results:
